Claims

[Scope of utility model registration request]

(1) A spring fixed to a support member, a pulley connected to the spring, a winding mechanism unit that sequentially winds up a flexible continuous body hung on the pulley by motor drive, and detects the amount of displacement of the spring. A sensor unit that determines the magnitude of the load that can be applied to the flexible continuum, a load setting unit that determines the magnitude of the load that can be applied to the flexible continuum, and a detection output of the sensor unit and a set value of the load setting unit are compared with each other, and according to the comparison result, and a drive control section that controls on/off the motor of the winding mechanism section,
tension detection means for monitoring the flexible continuum and detecting that the tension has decreased to below a threshold; and when the tension detection means detects a decrease in tension, and/or driving the motor of the winding mechanism section. When the power is turned off, the motor can function as a power generation brake, and when the motor of the winding mechanism section starts or restarts driving, the torque of the motor gradually changes to the load setting. and a time constant adjusting means that functions to reach a set value of the zero balancer.

(2) When the drive power of the motor of the winding mechanism section is turned off, the load setting section sets the load applied to the flexible continuous body to zero, and the slack control means controls the winding process. A zero balancer as set forth in claim (1) of the utility model registration, characterized in that the motor of the mechanism section is configured to function as a power generating brake.
